Introduction to Cement Screw Conveyor

A cement screw conveyor is a specialized device used in the construction industry and material manufacturing plants to transport cement, sand, powder, and similar materials.

Working Principle

The working principle of a screw conveyor is as follows:

• Cement material is fed into the inlet of the screw conveyor.

• When the screw shaft rotates, the screw flights push the cement material to move linearly along the trough.

• The cement material is discharged through the outlet of the screw conveyor.

Structure of Cement Screw Conveyor

Below are some details about each part of the cement industry screw conveyor:

• Trough: The body of the screw conveyor, made of U-shaped steel or steel pipe.

• Shaft: The central part of the screw conveyor, made of pipe or solid steel.

• Screw Flights: Helical blades mounted on the screw shaft to push the material forward.

• Motor: The drive unit of the screw conveyor, enabling the shaft to rotate and move materials.

Technical Features

High reliability:

• The outer tube is made of high-quality steel pipe, and the inner tube is made of space steel pipe, cut by CNC wire cutting machines and welded using CNC circular welding machines, ensuring straightness and high wear resistance.

• The flights are made from 6mm thick wear-resistant steel, ensuring durability and stability.

• The gearbox is high-quality, self-manufactured, with precision-ground gears, SKF bearings from Sweden, “Sidaxing” brand oil seals, a newly designed outlet cover, capable of transmitting high torque, with low noise, no oil leakage, and no dust leakage.

High adaptability:

• Double or triple pitch design reduces material compression during transport, preventing blockages.

• Universal ball joint technology at the inlet allows flexible installation and adjustment without dust leakage.

• Improved intermediate shaft suspension fixing method with additional anti-slip spring rings to prevent fixing ring failure and inner tube misalignment.

Applications of Screw Conveyors in the Cement Industry

• Transporting cement from silo to concrete mixer: Quickly and efficiently delivers cement from silo to mixer.

• Transporting cement from storage to production areas: Moves cement from storage areas to required locations in cement plants or construction sites.

• Transporting cement to packaging areas: Transfers cement from grinding sections to bagging stations in cement plants.
